Atomic Structure Nucleus Protons Neutrons Electrons

Atomic Structure ELECTRON Tiny, very light particles Have a negative electrical charge (-) Located in the Electron Cloud Orbit around the outside of the nucleus

Atomic Structure PROTON Much larger and heavier than electrons Protons have a positive charge (+) Located in the nucleus of the atom

Atomic Structure NEUTRON Large and heavy like protons Neutrons have no electrical charge Located in the nucleus of the atom

Mass of Sub Atomic Particles

Atomic Structure What limitations does this atomic model have?

Atom Compared to a Baseball Stadium If a marble representing the nucleus of an atom, is sitting on second base in a baseball stadium, the entire stadium would represent the size of the atom.

Atom – Penny Comparison If you enlarged a penny to the size of the United States, each atom in the penny would only be the size of a ping pong ball.

So there are the same number of atoms in a penny as it would take ping pong balls to cover the US!!!
